The holidays are coming and you're about to be photographed at every party you attend. What does that mean for you (other than blowing up Instagram with all of your soiree-appropriate sartorial choices)? Making your arms look amazing in every single snapshot, without needing to do the skinny arm pose.

Luckily, celebrity trainer Anna Kaiser of AKT InMotion Studio in NYC shared four simple and super-effective arm workouts that don't even require leaving your house. Here, the four GIFs that'll get you Michelle Obama-like arms in no time.

1. The Warrior Press. Do 20 reps of this updated lunge move two times and you'll be feeling it in your triceps like no other. Make sure to lift your arms all the way up for the maximum arm-toning benefits.

2. The Lunge and Lift. You'll feel this move everywhere: your thighs, your ass, your core, your arms, your back — it's the perfect all-in-one workout. Over time, after doing 20 reps of these twice in a row, you'll be ready to show off your hot body in that backless slip dress. Warning: your friends will be jealous.

3. Flip-Flop Dips. This move gives you a little extra toning in your stomach and legs, as well as in your shoulders and biceps. Do 10 reps and switch legs. And try not to cry... because this position isn't an easy one to be in for long.

4. The Tripod Press. This one is tough, but totally worth it. Do 10 reps of these and switch to the opposite leg. Then, get ready for the "Oh my god, your arms look ridiculously toned," compliments to fly.
